I have had the same issue mutliple times. Each time I have never physically forwarded the phone and I have to shut down the phone to reset it. It is very disconcerting that this happens with no warning to the user.

I have been having this problem for the last two days at least. I called customer support earlier this morning and they enabled and then disabled call forwarding even though I did not set it in the first place. I restarted the phone and did get incoming calls after that. After some time I again had the same problem. I called customer support and they did the same thing again. I am getting calls for now. Not sure if I will have this problem after some time

Just went through 4 days of the same issue. Finally someone in tech admitted that Its a software problem and won't be fixed until the 2nd up date later this year. I've been told it's a Sim card/tower/ call forwarding issue. Tried all the fixes finally they admitted it's a device issue/software issue. They claim activating HD calling should patch the issue until the next update is released. They orrfered to replace my device but I'm returning it for a $275 credit and then I'm canceling my service. My issue has been on going since Nov 26, Cs had me activate visual voice mail and I had 14 VM in my inbox from Nov 26 never once did I receive a missed call or VM icon telling me they were there. Won't even know that I had this problem until my wife came home on Jan 17 telling me that she has called my cell phone for the last hour with no answer. You will never know that you're having issue as calls do come through and that this issue happens and goes unnoticed. Icing on the cake is when CS tech told me the problem was fixed and he would like to call my phone before we finish and make sure that it is working and the phone reverted back to not receiving calls. That was day three of tech support.

I thought this problem was fixed with the latest update but I just had the same problem reoccur after booting up my phone. I received a phone call about 20 minutes after start up and then 2 calls go straight to voicemail afterwards.
